#114867 - A bad tip that works Responding to: ???'s previous message |
At first I have difficulties in converting the Voltage value to something displayable. The other persons I knew use tables to represent the voltage. But then I try this after reading the ADC0808 datasheet and it works. I increase the voltage reference (and also VCC of course) to 5.12V (it's still under the 5,5V of ADC's AMR). By using 5.12V I don't have to use the table because each step of the ADC would represent an 0.02V increment. And as Russel said, I use resistors to divide the voltage I want to measure. As far as I know, my ADC0808 is still working fine until now. |
